Facilitator Directions 
Purpose: 









This
activity is an optimization problem with lots of group interaction. It is designed to have students apply the rate
formula (r=d/t) to each of their group member’s tasks. The mission of
the group is to move equipment from one side of a river to the other in
1/2 hour. 










Supplies Needed: 








Calculators 








Pens 








Copies of Instructions 







Maps 

















Procedure: 








1 
Divide the class into groups of
5 or less (they do not have to be of equal size). 

2 
Give each student: 








a. The scenario 








b. A calculator 








c. An equipment
list 







d. A map 








e. Pens 







3 
Read the scenario and
instructions aloud while the students read to themselves. 

4 
Have
each member of the group roll a 6sided die to determine their
individual character attributes (repeats of the same attributes are
allowed). 
5 
After the character attributes are selected,
have the students calculate the maximum distance each member can cover
in 30 minutes. They will have 5 minutes
for this activity. 
6 
After 5 minutes have lapsed, direct their
attention to the equipment list and explain that they now need to
decide which ten pieces of equipment they feel are the most important
and who will retrieve the items. They will
have 5 minutes for this activity. 
7 
After the second 5 minutes have lapsed, announce
to the students that they need to implement their plans to retrieve the
items they decided on. The groups
now have 30 minutes to complete the challenge. 
8 
Help guide the students through the steps in the
exercise and in using the distance formula. 
9 
When the 30 minutes are up, the time can be
extended and the students can be encouraged to retreive more items, or
each group can be asked to share what their strategy was and what they
decided to save from the fire.
